The Auralux LED Grow Light Strip is a unique 5M (16.4') LED Strip light containing 3 Red (665nm) and 1 Blue (450nm) LED which works together with the Auralux line of LED Controllers. These strips are perfect for hydroponics because they are a high output strip, which produce very little heat. Custom controllers can be made to cycle the red and blue lights at separate times to mimic daylight and night time settings for various crops. The Color Ratio is adjustable with off-the-shelf LED controllers, but more sophisticated programming may be needed for certain plants.
